Silverlight is a browser plugin developed by Microsoft that allows creation of rich interactive applications and media experiences using HTML, CSS, and .NET languages like C# and VB. It provides a runtime for browser-based rich internet applications that can run across browsers on Windows, Mac OSX, and Linux. Silverlight applications are built with XAML markup and code files and use WPF and .NET frameworks to provide capabilities like media streaming, flexible programming models, and security.

1. A new dimension to the web

2. The Web and its new face Microsoft Silverlight Silverlight offerings The Implementation Silverlight Security Model Using Silverlight Demo

3. Static pages (HTML) , dynamic sites (DHTML) Legacy editors (notepad) JavaScript (client side scripting) ( fastest ) ASP.NET , PHP , Perl , Phython , Ruby , AJAX Flash , Flex , Java Applets (RIA’s) Dynamic editors ( VS 05’ , NetBeans , Flash ) Silverlight

4. Runtime for browser RIA’s Cross browser ( IE , Mozilla , Safari, ) Cross platform ( Windows , Mac OSX , Linux) Flexible programming model ( C# , VB , AJAX, Ruby , JavaScript ) Next generation media experiences (streaming audio , video ) Robust Security Model

5. Formerly called WPF/E ( Windows Presentation Foundation/ Everywhere) A part of the .NET 3.0 framework

6. BCL ( base class library ) – data access , reg exp, string handling DLR ( Dynamic language runtime)- allows dynamic compilation and execution of languages( managed JScript , IronPhython , IronRuby, dynamic VBx) WPF – the presentation tech in .NET XAML – the UI representation format Mini CLR – subset of the .NET CLR (yet robust) CoreCLR – Security Model AJAX , JavaScript libraries

7. Root HTML file – provides basic entry to browser CreateSilverlight.js – specify the controls size and reference the XAML Silverlight.js – instantiates the Silverlight control in the HTML page Page.XAML – defines UI of the page Page.XAML.cs – the event driven C# code

8. Compatibility Interoperability Light weight High performance RIA rendered Flexible programming model Mobile – Silverlight apps can be viewed on mobiles DirectX and Direct3D support Integrates with ease XAML can be crawled High speed video streaming , web media , gaming
